Scrusted Scabies

Scrusted scabies, also known as Norwegian scabies, is a severe and contagious skin infestation caused by the Sarcoptes scabiei mite. This condition is characterized by thick, crusty, and scaly skin lesions. In this article, we will provide simple, plain English explanations of scrusted scabies, including its types, causes, symptoms, diagnostic tests, treatments, and medications.

Types of Scrusted Scabies

There is only one type of scrusted scabies, also known as Norwegian scabies. Unlike typical scabies, which affects a smaller area of the skin, scrusted scabies is a more extensive and severe form of the infestation.

Causes of Scrusted Scabies

1. Sarcoptes Scabiei Mite: The main cause of scrusted scabies is the Sarcoptes scabiei mite, which burrows into the skin and lays eggs, leading to a severe infestation.
2. Weakened Immune System: People with weakened immune systems, such as those with HIV/AIDS, are at higher risk of developing scrusted scabies.
3. Poor Hygiene: Lack of proper hygiene can increase the risk of scabies infestation, including scrusted scabies.
4. Crowded Living Conditions: Living in overcrowded places, like nursing homes or shelters, can facilitate the spread of scabies.
5. Close Contact: Close contact with an infected individual can easily transmit the mites responsible for scrusted scabies.
6. Age: Elderly individuals and infants are more susceptible to severe forms of scabies, including scrusted scabies.
7. Mental Health Disorders: Individuals with mental health disorders may be less able to care for their hygiene, increasing their risk.
8. Physical Disabilities: People with physical disabilities may have difficulty maintaining personal hygiene, making them more vulnerable to infestations.
9. Medications: Certain medications, such as corticosteroids or immunosuppressants, can weaken the immune system and increase susceptibility to scrusted scabies.
10. Chronic Illness: Chronic diseases like diabetes or kidney disease can weaken the immune system, making individuals more prone to severe scabies infestations.
11. Malnutrition: Poor nutrition can weaken the body’s defenses, making it easier for mites to infest the skin.
12. Bedding and Clothing: Sharing contaminated bedding or clothing with an infected person can lead to scabies transmission.
13. Poor Sanitation: Living in unsanitary conditions can increase the risk of scabies infestation.
14. International Travel: Traveling to regions with a high prevalence of scabies can expose individuals to the mites responsible for scrusted scabies.
15. Excessive Moisture: Prolonged exposure to moisture can make the skin more susceptible to scabies infestation.
16. Chemical Exposure: Contact with certain chemicals or irritants may make the skin more vulnerable to scabies.
17. Skin Conditions: Pre-existing skin conditions, such as eczema or psoriasis, can create openings in the skin that facilitate mite infestation.
18. Sharing Personal Items: Sharing personal items like towels or razors with an infected person can transmit scabies mites.
19. Occupational Risk: Some occupations, such as healthcare workers or caregivers, may be at higher risk due to frequent contact with infected individuals.
20. Inadequate Treatment: Incomplete or improper treatment of scabies can lead to a recurrence, which may progress to scrusted scabies.

Symptoms of Scrusted Scabies 

1. Thick, Crusty Skin: Thick, scaly crusts that cover large areas of the skin are a hallmark of scrusted scabies.
2. Intense Itching: Severe itching, often worse at night, is a common symptom.

9. Nail Changes: Nails may become thickened and discolored.
10. Hair Loss: Hair loss can occur in affected areas.
11. Swelling: Skin inflammation may cause swelling.
12. Difficulty Moving: In severe cases, crusts can limit mobility.
13. Secondary Infections: Scratched skin can become infected with bacteria.
14. Fever: Infection may lead to fever.

Diagnostic Tests for Scrusted Scabies 

1. Physical Examination: A doctor will examine the skin for characteristic signs of scrusted scabies.
2. Skin Scraping: A skin scraping may be taken and examined under a microscope to detect mites or their eggs.

5. Wood’s Lamp Examination: A Wood’s lamp may be used to check for fluorescence, which can indicate scabies.
6. PCR Test: Polymerase chain reaction (PCR) tests can detect the DNA of scabies mites.
7. Skin Culture: A sample of skin may be cultured to identify any bacterial infections.
8. Blood Tests: Blood tests can help identify underlying conditions or immune system disorders.
9. Allergy Testing: Sometimes, allergic reactions to mite proteins can be tested through blood samples.
10. Scabies Ink Test: This involves applying ink to the skin, which mites may burrow into, making them visible.
11. Skin Swab: Swabbing the skin may help collect mite samples for analysis.
12. Tzanck Smear: A sample of fluid from a blister or sore may be examined for mites.
13. Immunological Tests: Some tests measure the body’s immune response to scabies.
14. Patch Testing: Patch tests can help identify allergic reactions to scabies mites.
15. X-ray: In severe cases, X-rays may be done to check for lung involvement.
16. CT Scan: A CT scan can help assess the extent of skin involvement and identify complications.
17. Ultrasound: Ultrasound may be used to examine underlying tissue damage.
18. Electron Microscopy: In rare cases, electron microscopy may be used to visualize mites at a microscopic level.
19. Skin Prick Test: This test assesses the skin’s response to scabies antigens.
20. Serological Tests: Blood tests may detect specific antibodies related to scabies infection.

Explanation in Simple Terms

Scrusted scabies is a severe skin condition caused by tiny mites that burrow into the skin, leading to thick, crusty, and itchy skin. It can affect anyone but is more common in people with weak immune systems, the elderly, and those living in crowded or unsanitary conditions. Sharing personal items or close contact with an infected person can easily spread the mites.

Symptoms include intense itching, thick crusts on the skin, and open sores. Diagnosis involves physical exams, skin scrapings, and various tests to confirm the presence of mites. Treatment typically includes prescription medications, cleaning the environment, and isolation to prevent further spread.

Common medications for scrusted scabies include topical creams like permethrin and oral medications like ivermectin. Lindane lotion may be used in stubborn cases. Other treatments include antibiotics for infections, corticosteroids for inflammation, and emollients to soothe the skin. It’s essential to follow hygiene and cleaning practices to prevent reinfestation and educate affected individuals about scabies prevention.
